This is my friendly guide to a little twist I put in my personal r-hop installs that seems to make the install 200% faster and 150% better. If you read anything in here that doesn't make sense to you, or you would just like more information than what the guide gives you, feel free to pm me and I will see if I can help clear things up.
So here is the big secret... DO NOT SAND THE CONTACT PATCH OF ANY R/ER/IR-HOP PATCH!! For some of you this won't be a secret at all and you will stop reading by the end of this paragraph. However, for some of you this will be news. You might be thinking, "Well what if my bb's get stuck in the barrel or my gun overhops .43's with the hopup off??!!?!" Well your questions will be answered in the following paragraphs...
First thing is first, buy the appropriate z-kit for whatever r-hop type and size you need. The z-kit is not necessary, but since they are so readily available I will assume that is what you got ahold of.
Next you need to choose the tallest hopup patch. By "tallest" I mean the one that sticks up out of the window the farthest, and not into your barrel at all. The correct patch will allow your bb's to just roll down the barrel after it has been fitted into the window and should not touch the bb's at all.
Now for the surprise... rather than trying to make sure you sand the inside of the patch to a perfect sheen and still allow the patch to be consistent, cut down the outside of the patch. You should cut the non-contact side of the patch to fit flush with the barrel as if it were a part of the barrel. This will require turning it on its side and basically filleting the patch. It does not have to be pretty on the top non contact side. Just be sure not to nick the contact patch or cut too deep.
Now you have an r-hop patch that may not look the prettiest from the top, and you can sand the top of the patch down to make it look more appealing... but you will have a perfectly even, untouched contact patch that will give you amazing results.
EDIT: clarification
So I just want to clarify what I basically do. I make sure my patches are too tall so they do not contact the bb at all when installed, but stick up out of the window.
I then cut down the patches on the top non contact patch side to allow the hopup rubber to fit over them without pushing the contact patch into the barrel and making it come into contact with the bb.
This method is heavily reliant on a correct size M nub install, as it will need to push on the entire part of the patch that will come into contact with the bb. That being said if you do it correctly it will be much more consistent than any r-hop patch that has had its contact patch fiddled with and sanded.

Now I also do my M nubs a bit differently. If you have an r-hop that is already installed and always shoot the same weight bb, or want an easy adjustment of the hopup for one specific weight you can trim your hopup nub. I have mine trimmed down so when I turn my hopup all the way up, for the most hop it can give, it will hop .3g bb's perfectly. (I only shoot bioval or rice bag brand .3's) Now I cannot shoot .32's or .43's with a perfect hop anymore (without replacing my M nub which is easy) but I know that my hopup just needs to be turned up all the way and there is no more fiddling with it during games or worrying about it being loosened. You can also shoot any lighter weight bb's this way as well, Since your hopup patch should not be contacting the bb at all with the hopup turned off as I told you in the above r-hop install guide. You need to just bump your hopup on a bit and you can shoot .2's out of your awesome r-hop'd gun with no trouble minus that involved with light weight bb's. On occasion I do this at our indoor cqb field because .2's are available for $6 per 5000rd bag on evike at times and I do a lot more shooting than normal.
If you have made it this far thank you for reading! If your ever headed to an OLCMSS op, or anything in illinois, message me and I'd love to show you what kind of usability I got out of this method in my gun.
